Just tried my first shot at welding some cracks in my fenders. I have a nice soldering tool that allows me to control the temp. Did some reading and found out that around 575 degrees is a decent point to start. Melting works well at that temp. First I tried to lightly melt the top and under side of the fender. Looked very nice, but I wanted to see how it would hold up. So I hit it pretty hard with a broomstick. Did not hold at all and completely split back apart. Not really sure what I was expecting.
Try number two. Completely melted through about every 1/8" apart and melted it smooth over the top. From the back side it looked like someone had sown it together with thread. Melted that smooth and filled in some holes where it had been stitched with zip ties with a scrap fender I had. Smacked that with the broomstick and it held. So then I got a little aggressive with it and bent it around pretty hard. To my surprise it held. Only time will tell if its going to hold up.
Here are the before and after photos. 235169235170
I did use a utility knife blade to shave down the rough parts of the melting to get the final look above. Maybe I'll try the Dremal tool to smooth the rest of that out.
